From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
In case ravb_phy_start() returns with error the settings applied in
ravb_dmac_init() are not reverted (e.g. config mode). For this call
ravb_stop_dma() on failure path of ravb_open().
Fixes: a0d2f20650e8 ("Renesas Ethernet AVB PTP clock driver")
